What materials should be chosen for concentrated sulfuric acid at 400 degrees Celsius?
Thread Content
As the title suggests, the medium provided by the user is concentrated sulfuric acid at a temperature of 400 degrees. What materials can be used? Which grade of carbon steel or stainless steel is suitable? Our designers are not sure about this, so we’re asking the experts here for help.

Apart from silicon carbide, it’s estimated that nothing else will work; high-silicon cast iron might work, so it’s worth giving it a try.
400°C sulfuric acid materials: 304 iridium-plated, SiC, quartz glass, glass, Si3N4, Sallon, 304 lined with polybenzimidazole, Alloy33.
